Magnesium-dependent ATPase Activity and Cooperativity of Magnesium Chelatase from Synechocystis sp. PCC6803

The first committed step in chlorophyll biosynthesis is catalyzed by magnesium chelatase, a complex enzyme with at least three substrates, cooperative Mg2+ activation, and free energy coupling between ATP hydrolysis and metal-ion chelation. A detailed functional study of the behavior of the intact m...
